WILLIAM KOEDDING, OF ST. LOUIS, MISSOURI.

AUTOMATIC FILLING-MACHINE.

SPECIFICATION forming part of Letters atent No. 747,729, dated December22, 1903.

Application filed September 8, 1902. SerialNo. 122,477. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM KOEDDING, a citizen of the United States,and a resident of the city of St. Louis and State of Missouri, haveinvented a new and useful Automatic Filling-Machine, of which thefollowing is a' specification.

My invention relates to machines for filling bottles and otherreceptacles with liquid, and has for its principal objects to produce afilling-machine which will operate automatically when the Vbottle ispressed against it i-n proper position to be filled, to equalize thevpressure in the bottle with the pressure in the supplypipe before thesupply-pipe is opened to permit the liquid to How into the bottle, toprovide for automatically stopping the flow of the liquid when thebottle is filled, and to prevent any stale liquid getting into thebottle.`

' of a hollow cylindrical thimble or guide 1,

which has a iange 2 on its upper end and projects downwardly through' ahole inthe table or other suitable support 3, to which it V tutes afulcrum for a lever 6.

is firmly clamped by means of a nut 4, working on a thread on theexterior of said thimble.l Extending upwardly from the flange 2 is anupright or-supporting arm 5, which constithe vertical thimble is ahollow cylindrical slide 7, whose upper end is closed and provided withan arm 8. This arm extends lat-` erally and upwardly and is pivotallyconnected with the lever 6 at a point about midway between the fulcrunnor seat of thelever and the prolonged axis of the slide. Extendinglongitudinally throughthe slide is the liquid-supply pipe 9. Thissupply-pipe/Q is provided with a collar 10, which is ad'justably clampedthereto a suitable distance above the end of the slide. This collar ispivotally connected with the lever 6 by a pin or other suitable means.The pipe 9 is provided with a second collar l1, arranged to move up andWorking inl l down inside of the slide 7. This last-mentioned collar 11-forms the lower abutment for a helical spring 12, whose upper end bearsagainst the end portion of the slide 7, surrounding the inlet-pipe. pThe lower end of the slide7 is screw-threaded'to` fit into a body-piece13, which is hollowed out and threaded to receive it. The inlet-pipe 9extends downwardly a suitable distance 'beyond this body-piece, and theinner edge of its lower end is beveled off to cooperate with anadjustable seat 14 provided therefor. This seat consists of asoft-rubber plug secured in a cap-piece orclosure 15,which is threadedto engage a thread provided there-l for on the end of a tube 16, whichis fixed to the body-piece 13 and forms a casing or guide for thesupply-pipe 9. This last-mentioned tube 16 has one or more perforationsor ports 17 near its lower end in position to be traversed or coveredand uncovered. by the lower end of the supply-pipe 9. Surrounding theupper end of the tube 16, where'the tube enters the body-piece, is acylindrical sleeve 18, which isprovided'with one or more slots orpassage-ways 19. These slots or passage-ways 19 extend upwardly from apoint below the body-piece to a passage-way 20, arranged horizontallyvtherein and obviously may be formed in the body-piece itselfand thesleeve 18 thereby dispensed with. This pas-- sage-way 2O communicateswith achamber 21, which is provided with a float 22, adapted to closethe port 23 at the top of its chamber. From the port 23 at the upper endof the chamber 31 a passage-way 24 extends to a suitable point forconnection to the air-pipe 25. The several passage-ways are preferablydrilled in the body-piece 13, and the ends of the drillholes are closedby threaded plugs 26. The port 23 is controlled .by a valve 27, arrangedinsidel 'of the passage-way 24 and consisting of a plug whose lower edgeis beveled to conform to the beveled edge of port 23. Said valve 27 isprovided with a rodor stern 28,

rwhich extendsvertically beyond the turn of the passage-way 24 and astuffing-box 29, provided therefor. This valve-rod 23 .extends IOO 30,adjustably mounted thereon above said lever 6 or the collar 10, and isequipped with a spring 31, abutting upwardly against the same anddownwardly against a shoulder 32, provided therefor on the valve-rod 28.

The under side-of the body-piece 13 is pro vided with a soft-rubberwasher or ring 33, which surrounds the tube 16 and the sleeve 18thereon.

The operation of my machine is as follows:V The supply-pipe 9 isconnected with the lower portion of the tank of beer or other liquid tobe bottled, and the air-pipe 25 is connected to the upper portion ofsaid beer-tank. The bottle 34 to be filled is then placed around thetube 16 with its lip against the softrub ber ring 33. In the normalposition of the parts the supply-pipe 9 is closed at its end by means ofthe soft-rubber plug 14, and the air-pipe is closed by the valve 27. Thebottle is forced upwardly against the soft-rub ber ring, thereby sealingthe bottle from the atmosphere and at the same time forcing thebody-piece 13 and all the parts connected thereto upwardly. The upwardmovement of the bodyl thus eected is transmitted to the slide 7 andthrough it to the lever 6, and the movement of the lever carries with itthe supply-pipe 9 and the valve-rod 28 and the valve 27. The lifting ofthe valve 27 from its seat opens the air-pipe, so as to establish freecommunication between the upper end of the bottle and the upper end ofthe beertank through passage-ways 19 and 2O and the air-pipe. In thismanner the pressure inside of the bottle is equalized with the pressureon the beer in the tank, and consequently when the filling-pipe is openthe beer is free to flow by means of gravity without foaming or otherdisadvantages. The opening of the fi1ling-pipe results from thedifferential movement of this pipe with reference to its incasing-tube,and consequently such opening requires an appreciable time,whereas theair-valve is lifted directly from its seat. The proper timing of thesemovements is regulated by shifting the adjustable soft-rubber seat 14 bywhich the end of the fillingpipe is closed, the adjustable collar 50 onthe stern of the air-valve, or the relative positions of the connectionsto the lever 6 of the fillingpipe andthe stem of the air-valve. When thebeer has filled the bottle, it enters the passage-way 20 and through itthe Heat-chamber 21 and lifts the ioat against its seat, thereby closingthe port 23 and air-pipe 25 and cutting off the flow of beer.

TWhen the bottle is removed, the spring automatically returns the partsto their normal positions. In the returning movement the filling-pipe isclosed before the air-valve is seated. Consequently the beer in thepassageways of the body piece is forced out and the liability ofbecoming stale and getting into another bottle is thus prevented.

Obviously the construction hereinbefore described admits of considerablemodification without departing from my invention, and I do not wish tobe restricted to such construction. So, too, my machine may be used forfilling other receptacles besides bottles and with other liquids besidesbeer.
